Fixed – Mobile Over The TOP (OTT) managed services


4Talk4OTT is a fixed mobile complete solution for Telecom Operators.

4Talk lets Operators increase their bundle value and customer loyalty by “mobilising” fixed lines (or integrating mobile and fixed lines) into branded apps for smartphones and tablets.

4Talk is a combination of smart apps and an intelligent IP Core Network that can be integrated in a Telecom Operators network or deployed directly through Mondial Telecom’s cloud.
